Voluntary action acts as a slow response, due to many cells & synapses being involved, and its controlled by the cerebrum(forebrain), whereas reflex action has a fast response and is initiated by stimulation of receptor.

The sensory neurons carry nerve impulses from the receptor to the CNS(the spinal cord and brain). The role of motor neuron in a reflex arc is to control muscle movement. They carry messages from the CNS to the effector.
I chose this source because each diagram outlines the role of the neuron in the reflex arc.

The autonomic system is associated with involuntary responses, such as those related to homeostasis. It also targets the cardiac and smooth muscle, as well as the glandular tissue, through a balance of two divisions. The two divisions of the autonomic nervous system are the sympathetic division, which mainly responds to threats and gives the readiness to either confront the threat or run from it. This division is also called the fight or flight response. The sympathetic division causes the heart and breathing rate to increase, also causing sweat gland secretion to increase, hereby causing blood flow to the skeletal muscle to increase and blood flow to the digestive system to decrease, when the heart receives connection from it. The other division is called the parasympathetic division, which slows the heart rate, as it conserves energy, and increases intestine and gland activity, then relaxes sphincter muscles in the gastrointestinal tract. This division is also called rest and digest, as it controls the body's response while at rest. The parasympathetic division causes the heart rate to decrease, hereby increasing stomach movement and secretion. The autonomic nervous system is instrumental in homeostatic mechanisms in the body by balancing both divisions.
I chose this source because it provides credible information that relates and can be used in my work. The figure below illustrates the connections of parasympathetic division of the autonomic nervous system.

These impulses result from a difference in electrical charge across the plasma membrane of a neuron. The main function of neurons is to transmit signals from sensory organs such as the eyes and skin to the central nervous system, which is the brain and spinal cord, and from the central nervous system to the effector organs. each signal carried by the neuron is transmitted in the form of an electrical current, carried by the changes in potential difference, across the membrane of the axon. The synapse is where an axon terminal meet

The chemical molecule released then bind with receptors on the membrane of the other cell.
Many excitatory graded potentials have to happen at once to depolarize the cell body enough to trigger the action potential.
